What Are The Compositions of Human Semen?
The main component of semen are the sperms and about 80 million spermatozoa can be found in a milliliter of semen. Some properties of semen are as follows:
Color: Opalescent White
pH: 7.35 to 7.50
Specific Gravity: 1.028
There are many other components of semen which can be classified according to its site of origin: seminal vesicle, prostate, and bulbourethral glands. Seminal vesicle adds components to semen such as fructose, phosphorycholine ergothioneine, ascorbic acid, flavins, prostaglandins, and bicarbonate. Prostate gland secretes prostatic fluid, spermine, citric acid, cholesterol, phospholipids, fibrinolysin, fibrinogenase, zinc acid, and phosphatease. Bulbourethral glands secrete clear mucus during sexual arousal.
